Los Alamos biofuels program lead and NAABB executive director, Jose Olivares, says the group is targeting technologies from start to finish - from logistics, to feedstock preparation, to conversion and, finally, to distribution.

Algae can be modified to produce high-value chemicals, Olivares explains. Some algae produce molecules called keratinoids that are chemical products used in foods and dyes. The feeding and care of algae is one of the most interesting areas of this research. (
